Under which of the below conditions will natural selection be least likely to result in adaptation?
a. low genetic diversity
b. low species diversity
c. low ecosystem diversity
d. high species diversity

a. Low genetic diversity

Explanation:

Natural selection is the process of differential survival and reproductive rates among the individuals of a population. Natural selection works on the existing genetic diversity of the population and favors the genetic traits that impart survival advantage to the individuals.

In the absence of genetic diversity or low genetic diversity in a population would not allow the natural selection to increase the frequencies of the alleles responsible for adaptive genetic traits. This would pause the process of evolution carried out by natural selection.
